A TTORNE Y Patented Dec. 1, 1931 CHARLES W. CURLE, OF SAN. FRANCISCQ'CALIFORNIA FEED MECHANISM Application filed May 26, 1930. Serial No. 455,663.

This invention relates to improvements in feed mechanism for slug trimming machines. The principal object of this invention is to provide a device which will separate slugs so '5 as to feed them singly through a slug trimming mechanism.

Another object of the invention is to produce a device which is capable of operating upon a galley full of slugs of various thicknesses.

A further object is to produce a device which will operate upon a galley of slugs of various lengths.

A still further object is to produce a machine which is economical to manufacture,

one which is simple in construction and therefore will not become easily deranged.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, 7

Figure I is a fragmentary top plan view of the feed mechanism,

Figure II is a cross sectional view taken on the line 2-2 of Figure I, and

Figure III is a cross sectional view taken on the line 3-3 of Figure I.

In the trimming of slugs for printing, the

slugs are usually positioned in a galley which is a tray employed by printers and is therefore necessary to remove these slugs from the galley and to pass them past a trimmer head as called for in my co-pending application, Serial No. 451,710. In order to move these slugs individually a mechanism must be provided which will operate upon the individual slugs irrespective of their length or thickness, it being understood that these slugs vary in length and in thickness.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a support such as a table top as a whole. This top has a raised portion 6 and depressed portion 7 separated by a ledge 10. Along one side of the raised portion 6 is secured a rail 8 against which the upstanding side 9 of the galley 11 rests. This galley contains a plurality of slugs 12 which are held against a stop 13-by a spring pressed plunger 14 whichis carried in a movable arm 16. which may be moved along 56 the rail8 so as to keep a constant pressure against the slugs. A pawl 17 pivoted to an oscillatingjarm 18 has its nose riding upon the stop 13 and overlying the edge of the stop as illustratedinFigure I so as to engage the slug A when it is moved toward the left of the drawing. V

Asthe arm 18 is oscillated, the slug A will be moved to the dotted line position B in which position it will lie upontthe elevated surface 6 and free of the stop 13. The actionof the spring pressed plunger 14 will now cause the slug to move from the position B to the position G and in making this movement the slug will drop upon the depressed portion 7 and between the raised portion 6 and a guide 19. From this point the slug is moved forward by any suitable feed mechanism as for instance that illustrated in my co-pending application.

It will thus be seen that with this arrangement I can remove from a stack of slugs, one after another which slugs will be dropped to a lower level and then advanced for treatment and that by this arrangement the length of the slug or thickness of the slug does notralter the operation of the derace.

It is to be understoodthat the form of my invention herewith shown and described is 35 to be taken as a preferred example of the 1 same and that various changesrelative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. In a slug separatingdevice, a support having an elevated surface and depressed surface, a stop positioned adjacent said elevated surface, means for moving a plurality of slugs against said stop, a reciprocating arm mounted on said support, means carried by said reciprocating arm for engaging the slug contacting said stop for the purpose of moving said slug endwise with respect to the other of said slugs positioned on said support for the purpose specified.

2. In a slug separating device, a support having an elevated surface and depressed surface, a stop positioned adjacent said elevated surface, means for moving a plurality of slugs against said stop, a reciprocating arm mounted on said support, means carried by said reciprocating arm for engag-- I ing the slug contacting said stop for the purpose of moving said slug endwise-with respect to the other ofsaid slugs positioned on said support, and a guide carried onsaid depressed portion adapted to position the separated slug.

3. In a slug separating device, a support, a depressed portion, an elevated portion,

said portions being separated by a ledge, a it stop carried on said support and positioned adjacent said ledge, a pawl adapted to move over said stop, a rail carried on said sup port, spring means carried by said rail and adapted to engage av plurality of I slugs mounted on said raised portion,- means for reciprocating said pawl to cause endwise movement of one of said slugs to move said slugs from said elevated portion to said depressed portion.

In testimony whereof I afiiX my signature.

CHARLES GURLE.
